20090047960 | Closed subscriber group cell handover - A radio terminal connection may be handed over from a serving base station associated with a serving cell to a closed subscriber group (CSG) cell served by a CSG base station in which only radio terminals belonging to the CSG are permitted to access and receive service from the CSG cell. Radio terminals in the serving cell are generally informed not to report to the serving base station signal quality measurements of signals transmitted by CSG base stations. But if a radio terminal in the serving cell is authorized to access and receive service from the CSG cell, then that radio terminal is instructed to report to the serving base station signal quality measurements of signals transmitted by the CSG base station. Based on that report, the connection may be handed over to the CSG base station. A central node provides a CSG authorization list identifying CSG authorized radio terminals to the serving base station when a listed CSG cell is a neighboring cell which the radio terminal is authorized to access. | 02-19-2009 |
20090047968 | NEIGHBOR CELL RELATION LIST INITIALIZATION - Neighbor cell relation lists are initialized and managed in various ways that are especially beneficial to closed subscriber group (CSG) cells served by CSG base stations. Typically, only a radio terminal belonging to the CSG is permitted to access and receive service from the CSG cell. As a result, information is provided to radio terminals in the cells neighboring the CSG cell that generally indicates that radio terminals are not to report to a respective serving base station signal quality measurements of a signal received from the CSG base station unless the radio terminal is a member of the closed subscriber group for the CSG cell. When a CSG cell is powered-up, it is determined whether the CSG cell has previously been powered-on in the same environment. If so, the neighbor cell relation information for the CSG cell is updated with other network node(s). If not, neighbor cell relations of the CSG cell are initialized. In one example, when a new neighbor cell relation has been added to its neighbor cell relation list, the CSG base station inherits neighbor cell relation list entries from the newly-added neighbor cell. | 02-19-2009 |

This is achieved by including uplink grant availability into the channel state feedback reporting triggers used for determining when and how to send channel state feedback from a UE, i.e. a channel state feedback reporting request may be sent by a base station in an uplink grant to a UE comprising an indication of an expected amount of information to be returned. | 02-26-2015 |
20150085769 | TECHNIQUE FOR OPERATING A NETWORK NODE IN A HETEROGENEOUSLY DEPLOYED NETWORK - A technique for operating a network node in a heterogeneously deployed network comprising network nodes of different nominal transmit powers and at least partially overlapping coverage areas is described. A method implementation of this technique comprises a step of operating the network node in a base mode in which the network node is configured to transmit terminal-specific demodulation reference signals for a first set of terminal devices. The method comprises the further step of selectively activating or deactivating operation of the network node in a Single Frequency Network (SFN) mode in which the network node is configured to transmit, for a second set of terminal devices, the same cell-specific reference nodes as another network node of the heterogeneously deployed network that has a larger nominal transmit power. | 03-26-2015 |
